So I finished Between. It was ok. The second season started picking up a little steam, but it's no Leftovers. They just never developed the characters enough or have us care enough about their threat. Best character was the younger kid Harrison.
Started stranger things. 4 episodes in this is great! Definitely poltergeist/ET/Alien. They have the 80s vibe captured perfectly. The soundtrack and the score are perfectly done also.
